DOMESTIC HEATER.

SPECIFICATION forming part of Letters Patent No. 627,753, dated J une 27, 1899. Application led November 23,1898. Serial No. 6r97,224. (No model.) v i To au whom it may concern:

Be it known that LA'WILLIAM I-I. H UBBARD, OF JAS. N., a citizen of the United States, residing at Cambridge, in the county of Dorchester and State of Maryland, have invented certain new and useful Improvements in Domestic Heaters, of which the following is a specification.

This invent-ion relates to a portable domestic water-heater applicable to the tops of ordinary kitchen stoves or ranges, a warmingoven over the water-heater, and means for filling the water-heater without removing the 'warming-Oven.

The invention is illustrated in the accompanying drawings, in which-.-

Figure 1 is a perspective view of the complete apparatus, a portion of the front being broken away to expose the interior. Fig. 2 is a horizontal section of the Awater-heater on the line 2 2. Fig. 3 is a sectional detail view of the device for supplying water to the heater while the warming-oven is in position.

The lower chamber or water-heater comprises an oval or oblong shaped boiler A, having a central vertical iiue B extending through it from top to bottom. This iiue should be the same size in cross-section as the ordinary sheet-iron smoke-flue of a kitchen-stove. The flue is secured water-tight to the bottom c of the boiler, which is fiat to set upon the stove-` top, and the lower open end of the flue will. it over the upward ilange that usually surrounds the smoke-pipe hole of a stove. Several short pipes d d pass horizontally through and cross each other in the smoke-fl ue, to which they are fitted water-tight, and both ends of these-pipes are open in the boilerchamber. The smoke and heated products of combustion passing up the flue B impart heat quickly to these short pipes, and thereby heat the water. The upper end e of the smokefiue serves for the attachment of the ordinary smoke-pipe B. The upper chamber or Warming-oven F sets upon .the boiler4 or heater A and serves as a cover therefor and entirely closes it. This Oven has doors g in its side and a vent-slide h in the upper part of its end. The smoke-line also passes up through the oven and is connected at the top with the ordinary smoke-pipe B.

A filling device is provided to enable the boiler tO be replenished without disturbing the oven and consists of a hinged or tilting lip I,fitted to an opening in the wall of the boiler. This lip has a pivot j at its bottom and side iianges lo and is adapted to incline outward when in the open position, (see Fig. 1,) at which time water may be poured into the lip to supply the boiler.A The lower edge of said lip laps down on the inner side of the said wall and makes a water-tight joint when filling. The side flanges have each a laterally-projecting lug l, which prevents the lip fromA tilting Out too far. When the lip is pressed inward, it becomes iiush or even with the wall, (see Fig. 3,) and thus closes the opening in the wall and prevents steam from escaping. v i

The boiler has a spigot m for drawing hot water.

The usefulness and advantages of a combinedboiler and warming-oven of this construction are obvious.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is-

A portable heater adapted to rest on the top of a stove comprising4 the combination of an upper and lower chamber; a vertical smokepipe secured water-tight to the bottom of the lower chamber and extending up through the upper chamber; and an opening in the wall of the lower chamber provided with a hinged v Or tilting lip to tilt outward when open, and` the lower edge of said lip lapping down on the inner side of the said wall to make a water-tight joint when lling, whereby the lower chamber may be filled without disturbing the.
